Berezinskii-Kosterlitz-Thouless Quantum Supercriticality in XXZ Heisenberg Spin Chain
Haoshun Chen, Enze Lv, Ning Xi +2
Quantum fluctuations can give rise to a singular quantum critical point (QCP) in the ground state, whose influence extends to finite temperatures, forming a quantum critical regime…
RKKY-dipolar Interactions and 3D Spin Supersolid on Stacked Triangular Lattice
Ning Xi, Xitong Xu, Guoliang Wu +9
Inspired by the recent discovery of metallic spin supersolidity and its giant magnetocaloric effect in the rare-earth alloy EuCoAl [Nature 651, 61 (2026)], we perform a com…
Electrical Transport and Quantum Oscillations in the Metallic Spin Supersolid EuCo2Al9
Xitong Xu, Yonglai Liu, Ning Xi +16
The discovery of spin supersolid and its giant magnetocaloric effect has opened a new arena in frustrated quantum magnets and cutting-edge cryogenics. The intermetallic EuCo2Al9 (E…
Spinons, solitons and random singlets in the spin-chain compound copper benzoate
Ying Chen, Guijing Duan, Yuejiu Zhao +15
The antiferromagnetic Heisenberg chain is a paradigmatic quantum system hosting exotic excitations such as spinons and solitons, and forming random singlet state in the pre…
Giant Magnetocaloric Effect in Spin Supersolid Candidate NaBaCo(PO)
Junsen Xiang, Chuandi Zhang, Yuan Gao +16
Supersolid, an exotic quantum state of matter that consists of particles forming an incompressible solid structure while simultaneously showing superfluidity of zero viscosity [1],…
Quantum Supercritical Regime with Universal Magnetocaloric Scaling in Ising Magnets
Enze Lv, Ning Xi, Yuliang Jin +1
Quantum critical points ubiquitously emerge in strongly correlated systems, with their influence persisting at finite temperatures and external fields. A paradigmatic example is th…
Magnetocaloric Effect of Topological Excitations in Kitaev Magnets
Han Li, Enze Lv, Ning Xi +4
Traditional magnetic sub-Kelvin cooling relies on the nearly free local moments in hydrate paramagnetic salts, whose utility is hampered by the dilute magnetic ions and low thermal…
Observation of a 1/3 Magnetisation Plateau Phase as Evidence for the Kitaev Interaction in a Honeycomb-Lattice Antiferromagnet
Yanyan Shangguan, Song Bao, Zhao-Yang Dong +24
Fractional magnetisation plateaus, in which the magnetisation is pinned at a fraction of its saturated value within a range of external magnetic field, are spectacular macroscopic…
